There are a number of non-French sources that also mention that while Smith was indeed given overall command on behalf of the Porte--noting that Smith's brother was the British ambassador to Istanbul, and this level of command irked Nelson quite a bit. These sources also are clear that Smith limited his "command privileges" to turning two warships broadside and effectively blowing Bonaparte's siege efforts into the dirt--or sand, in this case. The actual conduct of the approximately six-week siege of the fortress of Acre itself was left in the capable hands of al-Jazzar Pasha and Haim Farhi, plus Phelippeaux. I'd agree, however, that Phelippeaux had more to do with the success at Acre than Smith. I'd also point out that Smith's attitude toward the French soldiers in Egypt after Bonaparte's return to France was far more humane than Nelson's.
